P.J. Woltjer

I am a post-doctoral researcher at the Groningen Growth and Development Centre. As an economic-historian, I am interested in topics ranging from the study of productivity growth in the United States, the diffusion of technology in Europe, to the impact of international trade on development in Africa. The aim of this blog is to provide access to my published articles and working papers, as well as the unpublished datasets, source descriptions and statistical and analytical code underlying my research.

Working Paper: Jobs in Global Value Chains

New Evidence for Four African Countries in International Perspective

ABSTRACT: What is the potential for job growth in Africa under participation in global value chains (GVCs)? In this study the concept of GVC jobs is introduced which tracks the number of jobs associated with GVC production of goods. A novel decomposition approach is used to account for GVC jobs by three proximate sources: global demand for final goods, a country’s GVC competitiveness (measured as the country’s share in serving global demand) and technology (workers needed per unit of output).

Working Paper: The Economic Transformation Database

ABSTRACT: This note introduces the GGDC/UNU-WIDER Economic Transformation Database (ETD), which provides time series of employment and real and nominal value added by 12 sectors in 51 countries for the period 1990–2018. The ETD includes 20 Asian, 9 Latin American, 4 Middle-East and North African, and 18 sub-Saharan African countries at varying levels of economic development.

Column: Manufacturing Hope in Africa

On March 20th, The Economist featured research by the GGDC and UNU-WIDER on the manufacturing renaissance in Africa. A key finding is that the share of people working in manufacturing in sub-Saharan Africa has risen from 7.2% of the total in 2010 to 8.4%.

Article: Growth Accounting in Economic History

Finding, Lessons and New Directions

ABSTRACT: There is now a large volume of growth accounting estimates covering the long run experience of advanced countries. However, most of the studies in economic history are not based on state-of-the-art methods. There is a trade-off between maintaining international comparability and achieving the best results for individual countries. A one-size-fits-all approach Continue reading “Article: Growth Accounting in Economic History”

Article: The Impact of Sectoral Shifts on Dutch Unmarried Women’s Labor Force Participation

The Netherlands, 1812-1929

ABSTRACT: During the nineteenth century, Dutch female labor force participation (FLFP) was relatively low. Most scholars argue that social norms and rising wages were driving this development. However, their conclusions principally apply to married women. We study Continue reading “Article: The Impact of Sectoral Shifts on Dutch Unmarried Women’s Labor Force Participation”

Column: Historical Productivity Growth from Run of the Mill Industries

Evidence from the United States

Historically, productivity growth was not all about high tech sectors and research and development (R&D) expenditure. A new study published The Economic Journal finds that the great majority of productivity originated in other, more ‘run-of-the-mill’ industries. Continue reading “Column: Historical Productivity Growth from Run of the Mill Industries”

Article: The Composition of Capital and Cross-country Productivity Comparisons

ABSTRACT: The role of physical capital is typically found to be limited in accounting for differences in GDP per worker, but this result may be because capital is customarily assumed to be a homogenous unit. This assumption is misleading,  Continue reading “Article: The Composition of Capital and Cross-country Productivity Comparisons”
